A healthy diet is to eat with a balance (均衡) of various nutrition (營養) elements (元素). According to the diet pyramid (飲食金字塔), we should eat the kinds of foods with a proper (適當的) ratio (比例) so as to gain (得到) the necessary nutritions including carbohydrates (碳水化合物), calcium (鈣), fat (脂肪), protein (蛋白質), multiple vitamins (多種維他命) and fiber (纖維).

1. Whole Grain Foods to get carbohydrates for mainly energy.
2. Plant Oils to get fats , not all types of fat. Good sources of healthy unsaturated (不飽和) fats include olive, canola, soy, corn, sunflower, peanut, and other vegetable oils. These healthy fats not only improve cholesterol (膽固醇) levels, but can also protect you from heart diseases.
3. Vegetables (in abundance 大量) and Fruits (2 to 3 times). A diet rich in fruits and vegetables can decrease the chances of having a heart attack or stroke (中風); protect against a variety of cancers; lower blood pressure; help you avoid the painful intestinal (腸臟) problems or constipation (便秘).
4. Fish, Poultry (家禽), and Eggs (0 to 2 times). These are important sources of protein. A wealth of research suggests that eating fish can reduce the risk of heart disease. Chicken, the kind of white meat is also good sources of protein and can be low in saturated fat.
5. Nuts and Legumes (豆類) (1 to 3 times). Nuts and legumes are excellent sources of protein, fiber, vitamins, and minerals. As a snack (小吃), many kinds of nuts contain healthy fats, and packages of some varieties (almonds, walnuts, pecans, peanuts, hazelnuts). To eat occasionally (偶然), they are not that bad.
6. Dairy or Calcium Supplement (補充) (1 to 2 times). Building bone and keeping it strong takes calcium, vitamin D, exercise, and a whole lot more. If you enjoy dairy foods, try to select (選擇) those no-fat or low-fat products.
7. Red Meat: These sit at the top of the Healthy Eating Pyramid because they contain lots of saturated (飽和) fat. If you eat red meat every day, switching to (轉移) or chicken several times a week can improve cholesterol (膽固醇) levels.
8. White Rice, White Bread, Potatoes, White Pasta, Soda, and Sweets (Use Sparingly): All such kinds of foods are being stapled (分級) at the top as they can cause fast and furious (強烈的) increases in blood sugar that can lead to weight gain, diabetes (糖尿), heart disease, and other chronic (慢性病的) disorders.
9. Multiple (多種的) Vitamins: A daily multivitamin, multimineral supplement offers a kind of nutritional backup. 1. Details for your references (參考):
